Because sleeve gastrectomy is a restrictive form of bariatric surgery, the procedure does not require your intestines to be rerouted in the fashion of Roux-en-Y gastric bypass surgery. Since food passes through your digestive system in a normal manner, sleeve gastrectomy reduces your risk for long-term nutritional deficiencies, and does not require you to make future trips to your bariatric surgeon for post-operative adjustments.
Benefits associated with sleeve gastrectomy
Ongoing clinical studies continue to show that sleeve gastrectomy can help weight-loss surgery patients lose an average of 55 - 75 percent of their excess body weight within the first year following surgery. Sleeve gastrectomy can also help improve and reverse certain health conditions related to obesity, such as hypertension, obstructive sleep apnea, type 2 diabetes, infertility, joint pain, and more.
According to a study published in a 2013 issue of Annals of Surgery, sleeve gastrectomy is associated with higher patient safety rates compared to gastric bypass surgery, which is a malabsorptive form of weight-loss surgery. Compared to adjustable gastric banding, sleeve gastrectomy provides weight-loss patients with higher remission rates and overall better quality of life.
What to expect from sleeve gastrectomy surgery
Sleeve gastrectomy is often performed as a minimally invasive, laparoscopic surgery. During the procedure, your doctor will make a series of tiny incisions across your abdominal region. Then, a tiny camera is inserted into one of the incisions so your surgeon can fully view your abdomen and inner anatomy. Throughout the surgery, your bariatric surgeon will use tiny surgical instruments to remove part of your stomach. The end result will be a thin, vertical stomach pouch that resembles a sleeve. When surgery is complete, your surgeon will use a series of tiny sutures to close your incisions.
In most cases, sleeve gastrectomy takes between one to two hours. Because gastric sleeve surgery is a minimally invasive procedure, downtime and recovery is relatively speedy, and you can expect to experience little pain from surgery. Shortly after your sleeve gastrectomy surgery is complete, you’ll be released to go home so you can recover comfortably in your own home.
